Abstract (en)
[origin: WO9845755A1] A waterborne photoimageable composition or photoresist comprises a latex binder polymer based on a waterborne dispersion of a photopolymerizable urethane acrylate oligomer having sufficient carboxylic acid functionality to render it developable in alkaline aqueous solution and a photo initiator chemical system and other components to produce an aqueous coatable and alkali developable photoresist composition.
